MACHINE FOR THE MANUFACTUREOF MOSAIC FLOOR-CLOTH.

SPECIFICATION forming part of Letters Patent No. 523,610, dated July24,1894.

' Application filed Ma 29, 1294. Serial no. 505,624. (No model.)

To all whom it may concern.-

Be it known. that I, FREDERICK WALTON, a citizen of England, residing at114 Holborn, in the city of London, England, have invented certain newand usefulMachines for the Manufacture of Mosaic Floor-Cloth, of whichthe following is a specification.

My invention relates to the manufacture of mosaic floor cloth by unitingtogether and fixing on a suitable backing of woven fabric a number ofvariously colored pieces of compound material such as is used for makinglinoleum and such like floor cloths; I find that by using the compoundmaterial of four difierent colors I can produce a sufficient variety ofmosaic patterns. describe machinery according to my invention arrangedfor making mosaic patterns of four different colors, but it is to beunderstood that a like arrangement of machinery might be adopted fordealing with'a number of colors less or greater than four.

In the accompanying drawings-Figure 1 is a diagrammatic side elevationof the whole machine. Fig. 2 is a transverse section of one set of thefeeding rollers." Fig. 3 is aside Fig. 4 is a plan of the same. Fig. 5is a side view of the drum with the cutting, pressing and finishingrollers.

Fig. 6 is a longitudinal section of a set of the cutting cylinders andpressing rollers. Fig. 7 is a side elevation of the same. Fig. Sis

' an enlarged transverse section of a cutting cylinder, and Fig. 9 is anexample of mosaic pattern with the knives of the cutting cylinderarranged to that pattern.

As shown in Fig. 1 there are four elevators E, which may be of anysuitable known construction, and which raise from the lower parts of theapparatus those cuttings of material of the four different colors whichare not used in the mosaic pattern, along with such additions of freshmaterial in each case as may be necessary to make up for those portionswhich are used up in making the mosaic. These additions may however beseparately fed to the rollers.

of material are delivered from the elevators E into four sets of rollersR, more particularly described hereinafter, from which the material isin each case delivered in a continuous sheet I shall therefore Theseportions.

. S. The four differently colored sheets S pass down between a pressingroller P (see Fig. 5) and a cutting cylinder 0, by which the piecesrequired for the mosaic are cut out of the sheet and transferred tobacking B, while the waste pieces that is to say those which are .notrequired for the pattern are extracted from the cutting cylinder anddeliveredinto boxes eand conveyed by worms or otherwise to the bases ofthe elevator E to be carried up as above mentioned. The backing fabric Bis drawn from a reelband passes between the cutting cylinders and largedrum D from an apron d on which a more than half round a steam heateddrum 7 T between the surface of the drum and an endless apron A ofstrong fabric which is carried round by guide rollers and pressedagainst the drum T by rollers a, a. and. a After leaving the drum T thecontinuous sheet of mosaic M passes up over a guide roller m and down toa reel 7% on which it is wound along with felt or equivalent materialdrawn from a reel m to separate the convolutions of the mosaic andprevent them from adhering to one another.

The pressing roller a although it appears cylindrical in the drawings isreallypolygonal, with the sides of the polygon slightly hollowed so thatthe angles of the polygon act on the soft floorcloth material in such amanner as to tend to crowd portions of it as they pass along the sidesof the polygon somewhat closer together, forming slight undulationswhich are afterward leveled by the pressing rollers a If the rollera'were truly cylindrical, its action on the soft floor cloth materialwould be to force .it backward tending to detach it from the backing.

Such being the general arrangement and operation of the apparatus, Ishall now describe more in detail the construction and operations of itsseveral parts.

One of the sets of rollers R shown with its gear in Figs. 2, 3 and 4.operates as follows: The colored compound material in fragmentarycondition is fed between the heated rollers r r of which 0 is the coolerand the sheet delivered from them adheres to the cooler roller r or ifin excess rests on a stationary table T and the surplus is scraped 0E bya rapidly revolving scraper roller T The sheet after passing betweenrollers r and '1 passes over a roller r which may be termed themeasuring roller back over a roller '1' and down to the pressing andcutting rollers below.

In order to clear the sheet off the roller 0" a knife r is caused toreciprocate longitudinally against the surface thereof by means of aneccentric 1' which through a rod r and lever r communicates motion tothe knife 7". The several rollers are worked from the prime moving shaftB, through clutch R bevel gear R and train of cog wheels R. and Rdriving roller '2" and rollers r and r by gearing R and R The measuringroller r 'is driven by worm gear R from one of a pair of pulleys R and Rwhich are slightly tapered in opposite ways so that by shifting a beltalong them the speed of r can be adjusted. The scraping roller r isdriven by gear B. By means of hand wheels R and suitable intermediategear, worms' and worm wheels R are turned, turning screws to adjust thebearings of the rollers 'r' and r nearer to or farther from roller 7".

One set of the pressing rollers and cutting cylinders is shown in Figs.6, 7, 8 and 9. Sharp steel blades 0, arranged in form of a pattern suchas that shown in Fig. 9, project from the periphery of the cuttingcylinder. Some of the spaces between these knives, such as c thecuttings from which are to form tesserze of the pattern, are fitted withplates,

each having a central stud c with a spring which draws the plate 0 back.Behind each plate there are two sliding plungers 0 which pass throughthe shell of the cylinder and bear against an inner cam consisting of afixed part c c and a part 0 adjustable radially by screws 0 Above thecutting cylinder 0 is mounted the pressing cylinder P the periphery ofwhich 19 is of somewhat soft ma terial, preferably wood endwise of thegrain. On one side of the cutting cylinder is mounted a picking rollerF, and on the other side is mounted a scraping roller F. The operationwill be best understood by reference to Fig. 8. As the sheet S ofcolored material enters between the cutting cylinder O and the pressingroller P the knives c penetrate it dividing it into as many tBSSBItB asthere are spaces between the knives. These tesserae travel onward withthe cylinder until they pass between it and the picking roller F whichrevolves at the same surface speed as cylinder G and is provided withteeth curv ing a little forward in the direction of its rotation, theseteeth being so arranged on its periphery as to correspond only with thespaces between the knives containing tesserze which are'not to form partof the pattern. The teeth of roller F pick out these tesserze and carrythem round till the teeth pass through a comb plate (not shown) fixedbeyond said roller F, by which the withdrawn tesserze are cleared oifthe teeth thereof, and fall into the receptacle c (Fig. 5) to be carriedup by the elevator E. The tesserze such as c which are to form part ofthe patteen and which are not pulled out by the teeth of roller F,travel onward with cylinder 0 until they reach the part of itsrevolution where the sliding plungers c are acted on by the cam part aso as to push out the plates 0' and force the tesserze on to the sheetof backing B and the pins d which project through it. The tesserm thusdeposited on backing B which has the same surface speed as cylinder 0,travel onward with it to be joined by tesserze of other colors depositedon backing B in a similar manner. In case it should happen that any ofthe tesserze, instead of being deposited on backing B should adhere toone of the plates 0' it would be scraped off by scraping roller F beforereaching the pressing roller P, the machinery being thus saved from thedamage that would result if two thicknesses of material had to passthrough between the cutting cylinder and the pressin g roller. to keepthe plates 0' out until they have passed roller F the prominent part ofthe cam c is continued nearly to the top. Such pieces as may be caughtby scraping roller F can be removed by hand. The cutting cylinder 0 hason it a pinion C gearing with teeth on the circumference of the drum D.A pinion f on the picking roller F gears with pinion C, and similarly apinion f on the axis of roller F.

Having thus described the nature of my said invention and the best meansI know for carrying the same into practical effect, I claim 1. A machinefor the manufacture of mosaic fioor cloth comprising several sets ofrollers arranged to deliver sheets of colored floor cloth material to asmany sets of pressing rollers and cutting cylinders arranged partlyaround a drum provided with an apron having projecting pins, comprisingalso a reel to deliver backing fabric, a pairof pressure roll ers, aheated roller and set of pressing rollers with a traveling apron and itsguide rollers, a reel to receive the floor cloth along with suitablefabric interposed between its layers, substantially as herein described.

2. In amachine for the manufacture of mosaic floor cloth a set ofrollers for delivering a sheet of floor cloth material, consisting ofthree rollers r r r a stationary table 7*, a scraping roller r areciprocating knife 7'", a measuring roller 7* and a guide roller r inIt is for this purpose that in order combination with the gearing fordriving and adjusting them, substantially as described.

3. Ina machine for the manufacture of mosaic floor cloth the combinationof a pressing roller and cutting cylinder, the latter provided withknives, intermediate plates with their spring studs and plugers, and aninternal cam; a picking roller and scraping roller, substantially asdescribed.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 13th day of February, A. D.1894.
